RESUMEN
Two novel triterpenoid saponins, Snatzkein C, (3beta, 20-dihydroxylupan-28-oic acid 3-O-[beta-D-galactopyranosyl-(1-->2)-beta-D-glucopyranosyl-28- O-beta-D-glucopyranoside) and Snatzkein D, (3beta, 20-dihydroxylupan-28-oic acid 3-O-[beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl]-28-O-beta-D-++ +glucopyranoside), have been isolated from Arenaria filicaulis. Their structure and conformational behaviour were elucidated by one- and two-dimensional 1H NMR and 13C NMR spectroscopy.
